FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 406,375, dated July 2,18389. Application led December 13, 1888. Serial No. 293,463. (Nomodel.)

.To all whom, t may concern.:

Be it known that I, CHRISTOPHER STOCK- MANN, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented new and useful Improvements in Fountain-Pens, ofwhich the following is a specification.

This invention relates to that type of fountain-pens wherein thepen-holder and inkfeeder is arranged at one end of a hollow handle andis composed of a plug having an ink-duct and a slot, so that the ink issupplied to the back of the writing-pen by the action of the splitpen-point.

The object of my invention is to improve the construction of the feeder,whereby an increased quantity of ink can be caused to How to the back ofthe pen, when desired, without liability of blotting.l

The obj ect of my invention I accomplish by the features of constructionhereinafter described and claimed, reference being made to theaccompanying drawings, in which- Figure l represents a vertical centralsection. Fig. 2 is a transverse section in the plane a? Fig. l. Fig. 3is a similar section in the plane y y, Fig. l. Fig. 4 is an elevation ofthe feed-plug, showing its back. Fig. 5 is a similar view showing theface of the feed-plug.

Similar letters indicate correspondin parts.

In the drawings, the let-terA designates the usual hollow handle orreservoir to contain the ink, provided at its closed end with the usualnipple a, to receive the cap B when the pen is in use. The opening atthe other end of this handle is threaded to receive the penplug O, whichis hollow to receive the feedplug D and provided at its outer end with asocket b, similar to the pen-receiving sockets of ordinary pen-holders.

The feed-plug D is provided with a tongue c, which extends through thesocket b over the top of the pen E, so as to cover a portion of the slitof the pen, as shown inFig. l. The

body of the feed-plug D is cylindrical and made to fit snugly into thepen-plug C, and such feed-plug is formed or provided with twolongitudinal channels d d, terminating, respectively, at their outer endportions in openings e e, that extend transversely through the tongue c.rlhe channels d d are separated by a longitudinal rib d', extendingcontinuously between them and terminating beyond the transverseopenings. If a full supply of ink is required, both channels are leftopen; but if it is desired to reduce the supply of ink to the pen one ofthe channels is stopped up by a suitable plug.

At the inner end of the feed-tongue c is formed a shoulder g, and thepen is so adjusted that its tail end abut-s against this shoulder, ornearly so, and that the ink which passes from the ink-reservoir A downthrough the channels d passes through the openings upon the back of thepen,and then down between the feed-tongue and the pen, the flow of thepen being promoted by the motion imparted to the nib of the pen inwriting.

An air-hole f may be made in the concave portion of the pen-socket l) toprevent a vacuum in the ink-reservoir.

What I claim as new, and desire to secure by Letters Patent, is-

The combination, with the ink-reservoir A, of the pen-plug having apen-receiving socket, and the feed-plug made to lit the interior of thepen-plug and having two channels d d, separated from each other by anintervening ridge, and a feed-ton gue having two openings e e, one foreach channel, substantially as described.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
